JPH1075970A - End button for fixing rebuilt ligament dealing with cable - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to securly fix a rebuilt ligament by using a cable and to prevent a crimp for fixing a cable from coming into contact with the skin without nabbing even if the crimp is used near the skin at the time of drawing the fixed cable out of a bone hole. SOLUTION: This end button for fixing the rebuilt ligament dealing with the cable is the slender end button for fixing the rebuilt ligament having holes 7, 8 for drawing out the end button at both ends. The center of its body part 1 is provided with a valley part 2 for housing the crimp and both slopes of the valley part 2 are provided with holes 5, 6 for fixing the cable.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an end button for fixing a reconstructed ligament for a cable, which fixes the reconstructed ligament using a cable during a ligament reconstruction operation.

[0002]

2. Description of the Related Art Conventionally, when fixing a reconstructed ligament, an end button is used which is pulled out from a bone hole using a thread and fixed. However, the thread is weak in strength as a fixing material and may be cut or loosened early after the operation. Also,
Since ordinary threads are not captured in radiographs, even if they are twisted during surgery, or if they are cut or loosened after surgery, they will not be visible on radiographs. Therefore, these problems can be solved by using a metal cable instead of a thread. However, the conventional flat end button protrudes the cable fixing stopper (crimp) and is easily caught when pulled out from the bone hole, making it difficult to pull out. Also, when used near the skin, there is a disadvantage that the protrusion of the crimp hits the skin and causes pain to the patient.

[0003]

According to the present invention, the reconstructed ligament can be firmly fixed by using a cable, and when the fixed cable is pulled out from the bone hole, the crimp for fixing the cable is not caught, and An object of the present invention is to provide an end button in which a crimp does not hit the skin from under the skin even when used near the skin.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an end button for fixing a reconstructed ligament for a cable. In order to solve the above-mentioned problems, a valley 2 is formed in the center of a body 1 and surfaces 3 and 4 are formed. Drill holes 5 and 6 for cable fixing
(Or a hole 6), a cable is fixed in the valley 2 with a crimp, and a means for accommodating the crimp in the valley 2 is taken.

[0005]

According to the present invention, the above-described means are taken, so that in use, a cable for fixing a ligament is passed through the hole 5 (or hole 6) from the outside of the valley 2 and the cable in the valley 2 is used. Is fixed with a crimp, and the crimp is set in the valley 2.

When the cable-fitting end button for fixing a reconstructed ligament for a cable is passed through a bone hole, a thread 10 (or thread 9) for pulling out the end button is passed through a hole 8 (or hole 7) for pulling out the end button. Is passed through the bone hole first. Thread 10 while pulling the cable lightly in the opposite direction.
When the (or thread 9) is pulled, the end button can be passed through the bone hole in a state where the crimp is hard to be caught in the bone hole remaining in the valley portion 2.

[0007] When fixing a cable using an end button in a bone hole close to the skin, a crimp for fixing the cable is used.
Since the crimp is contained in the valley 2, the crimp does not easily protrude under the skin.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to the drawings.

FIGS. 1, 2 and 3 show an embodiment of an end button for fixing a reconstructed ligament corresponding to a cable. An elongated body portion 1 and holes 7 and 8 through which a thread for pulling out an end button is passed through both ends thereof.
Is provided. In the center of the body 1, a valley 2 composed of two facing surfaces having different inclinations is provided, and the facing surfaces are referred to as surfaces 3 and 4, respectively. A hole 5 for fixing the cable is provided at the center of the surface 3, and a spare hole 6 for fixing the cable is provided on the surface 4.
Is provided.

In the end button for fixing a reconstructed ligament for a cable according to this embodiment, the inclination of the surface 3 and the surface 4 may be the same, but one of the inclinations is stronger than that of the other so that the crimp for fixing the cable easily fits in the valley. It is desirable to do.

The end button for fixing a reconstructed ligament for a cable according to this embodiment can be formed of metal or synthetic resin, but is a titanium alloy which is safe and has high affinity for a living body, is radiographed, and has been developed for a biomaterial. It is desirable to use

In this embodiment, as described above, various cables and wires currently on the market are passed through the holes 5 (or holes 6) and fixed in the valleys 2 with crimps. The crimp can be stored in the valley 2.

FIG. 4 shows an embodiment in which the end button for fixing a reconstructed ligament corresponding to a cable is used, and an end button in which one end of a cable to which a ligament is fixed at the other end is passed through a hole 5 and fixed. Threads 9 and 10 for pulling out the end button are passed through the holes 7 and 8 of the end button, respectively, and the threads 9 and 10 are passed through the preformed bone holes. The bone hole must be relatively close to and larger in diameter than the width of the end button for later withdrawal and fixation of the end button. When the thread 10 is pulled with a slight tension applied to the cable, the crimp holding the cable is settled in the valley 2 and the end is attached without strong tension being applied to the cable attachment portion attached to the end button. The button can be smoothly passed through the bone hole. When the end of the end button with the thread 10 comes out of the bone hole, while pulling the cable 9 while applying a slight tension to the cable, the thread 9 is caught on the edge of the hole of the bone hole at both ends of the end button, and the cable is strongly pulled. It is the same as the conventional ligament-fixing end button using a thread that can be secured without coming off.

FIG. 5 shows an example of the use of the end button for fixing the reconstructed ligament corresponding to the cable near the skin. Since the crimp for fixing the cable fits in the valley 2, the crimp hits the skin from under the skin. It is less medically and cosmetically superior to conventional end buttons because it is less likely to protrude from the skin.

[0014]

As described above, the valley 2 is provided on the conventional end button, and the cable fixing holes 5 and
The provision of the hole 6 facilitates pulling out the end button, to which the cable has been fixed, which has been difficult in the past, from the bone hole, and crimps without protruding the end of the cable subcutaneously even near the skin. This has the effect of being able to be fixed.
